Wide inside knee area with half-inch thick padding to reduce side knee impacts. The interior of the knee area is lined with synthetic leather for durability and slip resistance. Addtional nylon webbing loops at the top of the thigh can be laced with skate lacing to help tie the units in place and keep them from slipping.
